Specilcation of Letters Patent.

Patented Nov. 18, 1913.

Original application filed November 9, 1911.` Serial No. 659,298. Divided and this application tiled Augiist 7,

To @ZZ '1o/1 om it may concern:

Be it known that I, JOHN E. CONZELMAN, a citizen oi' the United States, residing at the city of lVcbster Groves, in the county ot St. Louis and State of Missouri, have invented certain new and useful Improve ments in lVall Construction, (Case B,) of Wb ich the following is a specificatibn.

This aj'iplication is a division and a continuation of one tiled by me November 9, 1911, Serial No. 659,298.

This invention relates to concrete building structures, and has for its object to pio Vide a structure in which concrete slabs and columns are united to form a Wall having an air-space therein and being particularly adapted for cold storage plants, residences, and the like.

With this object in View, the present in vention consists of the novel features of construction and arrangement of parts, as Will be hereinafter more fully described and pointed out in the claims.

In the accompanying drawings forming part of this specification in which like numbers of reference denote like parts wherever they occur, Figure 1 is a side elevation of part of a Wall embodying this invention and including two columns and wall slabs con nected therewith; Fig. 2 is a sectional view on the line 2-2, Fig. l; Fig. 3 is a sectional 'View on the line 3 3, Fig. l; and Figs. 4, 5, 6, and 7 are detailed views of the form ot slab With an air-space therein used in this construction.

Each panel of the wall consists of a pair of columns or uprights 1 and a plurality of vertically-disposed slabs 2, the ends ot which fit in grooves 3 in the sides of said columns. Each slab 2 is preferably molded with a rectangular configuration and is formed in two members 4 and 5 which are preferably united integrally, as illustrated in detail in Figs. 4 to 7, inclusive. The member 4 is preferably Wider than member 5 and provided with a pair of flanges 6 that is ar'- ranged to extend vertically on a face thereof, one flange being located at one end of said slab and the other flange being located at the other end of same. The member 5 is preferably molded with a uniform thickness throughout and is united integrally with the fianges 6 on member 4, in the manner Serial No. 713,901.

about to be described, so as to leave an air4- space 7 between members 4 and 5.

The member 4 is molded first and, when the concrete is poured into the form 8 'of ahy desired construction, in 'order to forti) nnl? ber 5, the member 4 is placed so that its flanges 6 rest on the plastic concrete ill S'aid form, as best seen in Fig. 5. The concret@ in the :form 8 sets integrall with th facs' of the tiang'es 6 on membe 4 and tlibitl'r unites-said member 4 and member 5 integrally, so as to form the slab 2 hairirl'g ai air-space 7 between said member 4 and member 5. The member 4 may be so placed on the member 5 that either the top or the bottom of member 4 extends beyond the top or bottom of member 5, as illustrated in Fig. 7, so that, when the slabs 2 are placed one on top of another to form a panel, the ends of said slabs t in the grooves 3 in columns 1, and each slab joins the slab adjacent thereto by means of a rabbeted juncture. AS additional strengthening means reinforcing bars 9 are embedded in member 4, same being located near one surface of said inember and others near the other surface thereof. The ends of bars 9 may bend over rods 10, which extend longitudinally in flanges 6, and project from the faces of said flanges into member 5, as shown in Fig. 5, or, if desired, the bars 9 may terminate adjacent the ends of member 4 and the bars 10 may be arranged to extend through U-shaped bars 11 in flanges 6, said bars 11 being arranged so that their ends project from said flanges into member 5, as depicted in Fig. 5.

The columns 1 are preferably supported on a foundation l2, which extends underneath the lower slab 2. A rib 13 on said foundation fits in the lower part of the airspace 7 in the lower slab 2 and the members 4 and 5 ot said lower slab are preferably arranged so that the bottoms thereof are substantially flush, in order to rest on said foundation, as depicted in Fig. 2. It desired, the adjoining edges of each two adjacent slabs 2 and the ends of said slabs may be buttered with grout just revious to the placing of said slabs in position in the wall, so that, when said grout sets, said slabs are united integrally and said slabs and columns 1 are, also, united integrally, thus constituting a monolythic structure. The

bottoms of the lower slabs 2 of each panel may, also, be buttered with grut, which, when set, unites the lower slabs and foundation 12 integrally.

A Awall constructed of slabs having airspaces therein as hereinabove described is ynot only light in weight, but renders the space or room' inclosed thereby moisture prooi'. By reason of the slabs 2 being united by rabbeted joints, the junctures are thereby made secure and durable. The slabs and columns coperate and are interengaged: to

form a ri0'id,secure, and lasting structure thereinto whereby said bars serve to provide anchors for the second n amed slab.

2. In concrete "construction, a pair of spaced grooved columns, a series of hollow unitary slabs each composed of a pair of members, one of said members being longer Lthan the other member and having flanges on its inner face and at the ends thereof, the

\ ends of the longer member extending beyond the ,adjacent ends of the shorter member, the respective ends ofthe two members eX- tending in the grooves of the columns, the ends of the shorter member being spaced from the respective adjacent bottom Walls formed by the grooves of the column to form grout receiving space.

In testimony whereof I hereunto afixmy signature in the presence of tWo Witnesses. JOHN E. CONZELMAN. Witnesses:

GEORGE G. ANDERSON, WALTER C. GUELS.
